AppIicatioh filed December 20, 1920. Serial No. 431,948.

To all whom it may concern:

Be itknown that 1, JOHN B. ()Unrnnrrn, a citizen of the United States, residing at New Bedford, in the'county of Bristol and State of Massachusetts,' haveinvented new and useful Improvements in Stop ,Mecha nism for Looms, of which the following is a specification.

This invention relates to an improved stop mechanism for looms and has as its object the provision of certain improved features in a stop mechanism oithe typedisclosed in my co-pending application, Serial No. 307,591, filed June so, 1919. I

In the application above referred to there is disclosed a stop mechanism comprisinga kicker pivotally mounted uponthe protector rod of a 100m adapted to operate means upon the breast-beam which is connectedto the 'loom shipper-lever. The kickeris normally held in inoperativeposition, but is moved to position to actuate the shipperlever operating means when the shuttles are in certain defective and undesirable positions.

The present invention hasas one of its 0bjects the provision of an improved kicker device which is provided with a toe adapted to engage the shipper operating means upon the breast-beam, the toe being adjustable toward and from the breast-beam to accommodate the mechanism to looms in which the may be found desirable to locate this bracket, immediately adjacent the shipper, while in other looms, due to the proximity of the temple and other parts of the loom, a different position must be selected for the bracket. Hence, it is desirable that the connection between the kicker operated member and the shipper be adjustable in length to adapt the same to any selected position for the bracket supporting this member.

In my c of the toe in the'kicker arm. it may be moved The above and other obj ects'of the invention which are of a more obvious character will become apparent from a reading of the following description and an inspection of the accompanying drawings, in which:

Fig. 1 is an elevational view of the breastbeam of a loom showing my improved mechanism applied thereto.

Fig. 9- is a bottom plan of that portion of the mechanism shown in Fig. l; and i Fig. 3 is a verticalsectional view taken through the breast-beam and lay of a loom and showing the relation between that portion or the device supported upon the lay 7 and the mechanismshown in Figs. 1 and 2.

Referringto the drawings more in detail, A indicates the lay of a loom and B the breast-beam, the lay being" provided with the usual protector rod P which is shown as having thereon for pivotal movement the kicker 6 which has vertically extending arm 6 and a horizontally extending arm 6". The kicker isnormally movable about the protector rod by means of a spring 10 located between the vertically extending arm 6 and the lay. This movement is prevented by means of the ends 5of'ro'ck shafts, the opposite ends of which are located adjacent the shuttle boxes, except when the shuttle positions are defective. I

That portion of my mechanism which is above described is shown more clearly and is claimed in my co-pending, application. The kicker shown in the drawings is provided with a too 9 having a shank portion .9 which is adjustable in the endof the arm 6" of the kicker, the shank being threaded for this purpose. By adjusting'theshank toward and from the breast-beam and thus be suitably positioned and adapted to satis factory cooperation with the particular loom upon which it is positioned and withthe remainderofthe mechanism supported upon the breast-beam B. i The breast-beam has secured to one face thereof a vertically extendingbracket arm 11 as by means ofajbolt 19., and this'arm at its lower end is provided with a laterally extending portion 11' which terminates in a. substantially rectangular plate 13 having .at its rearend a lug 14 formed with an opening '15 therein. Supported upon the face of the plate 13 is a slide 16 having an elongated slot 17 therein through which extends a lug 18 upon the plate 13. A cotter pin 19 may dental displacement of the slide 16 from the lug 18. The upper edge of the slide 16 is cut away as at 16 to form a shoulder adapted to be engaged by the kicker toe, and the end of the slide may be formed with a tail piece or guide finger 17 extending through the opening 15. From the lower edge of the slide 16 extends an arm 20 which is formed with an upwardly extending portion 21 paralleling the face of the slide 16, and the upwardly extending portion 21 terminates ina rearwardly andlaterally extending arm 22 formed in one edge with a recess or seat 23.

The invention is characterized by the provision of an operating connection which is adjustable in length between the slides 16 and the shipper-lever S of the loom. Such a connection isv shown in the drawings and comprises a bell-crank 24 pivotally sup ported at 25 adjacent the slide so as to be removable and adjustable in' position so that it may always be located adjacent the slide. One arm of the bell crank extends into the recess 23 of the slide arm 22, and to its other end is removably connected a link 26 which has a looped end 27 fitting around a pin 28, at the end of the bell-crank. A cotter pin 29 may be passed through the pin 28 to prevent the link from accidentally falling from the bell-crank. The other end of the link is similarly connected to an eye bolt 28 adjustably threaded in an eye 29 of an arm 30 which has a pivotal connection 31 with a bell-crank 82 supported beneath the breast-beam at 33. The other end of the bell-crank 32 engages the dagger 84 pivotally supported in the usual manner upon the breast-beam, and adapted to engage and actuate the shipper-lever when operated V through the connection with the slide 16 7, above described.

From the above description, and from the dlsclosure in my co-pending application, it

will be understood that when there is danger of collision between shuttles upon the raceway by reason of the presence of a shuttle in a box at each end of the race-way, the shafts 5 will be rocked to permit the kicker. to'pivot about the protector rod P and to bring the toe 9 into engagement with the .shoulder 16 of the slide 16 upon the forward or picker motion of the lay. As the laymoves backwardly, thetoe of the kicker carries the slide rearwardly or to the left as viewed in Fig. 3, thus swinging the bell-crank 24 about its pivot and through the link connection shown causing movement of the dagger 34Cand of the shipper-lever.

- In applying the stop mechanism disclosed to a loom, it will be understood thatthe slide supporting bracket 11 will be placed in any desirable position along the breast-beam, adjustmentof the eye bolt 28 permitting variation of the distance between the bell-crank 2e and the bell-crank 32 in conformity with the selected position of the bracket. It will. also be understood that should it be found necessary to place the bell-crank at at any less or greater distance from the bell-crank 32 than is permitted by merely adjusting the eye bolt, the link 26 will be removedand a longer or shorter link substituted therefor.

It will be understood that this invention is not limitedto the specific details of construc tion constituting the embodiment of my invention shown in the drawings, and hereinbefore described in detail, but many modifi'cations might be made without departing from the scope of the invention which is more particularly defined in the claims.

I claim:
